Abstract

An actuation tool 10 is designed to produce movement between an upper member 12 carrying a multiplicity of sliding pins 15 (only one being shown) and a lower member 14 carrying a multiplicity of spring contacts 13 (only one of which is shown). Tool 10 is designed to both engage and disengage pins 15 and contacts 13. Lower member 14 has a transverse rectangular slot 16 and upper member 12 has a circular opening 18 overlying slot 16.

Actuation Tool

An actuation tool 10 is designed to produce movement between an upper member 12 carrying a multiplicity of sliding pins 15 (only one being shown) and a lower member 14 carrying a multiplicity of spring contacts 13 (only one of which is shown). Tool 10 is designed to both engage and disengage pins 15 and contacts 13. Lower member 14 has a transverse rectangular slot 16 and upper member 12 has a circular opening 18 overlying slot 16.

Tool 10 has a cylindrical shaft 20 of circular cross- section. The lower end of shaft 20 is designed to fit into opening 18. A cylindrical actuator pin 22 is fitted into shaft 20 so as to allow relative rotation therebetween. Pin 22 is located off center relative to the axis of shaft 20 to provide eccentric motion. The lower end of pin 22 has a downwardly extending tang 24 which fits into slot 16. The upper end of shaft 20 is connected to a slip clutch 26 which, in turn, is connected to a handle 28. Clutch 26 is designed to slip at a predetermined torque.

The upper member 12 is constrained to move linearly relative to the fixed lower member 14. When shaft 20 is inserted in opening 18 and handle 28 rotated, tang 24 slides back and forth in slot 16. When the tool is used to engage pins 15 with contacts 13, the tool is inserted as shown in Fig. 1 and handle 28 rotated causing upper member 12 to slide to the left as shown in Fig. 1 and thereby cam pin 15 into engagement with contact 13. The efficiency of applied torque in ac...
